Abstract

The invention discloses a display panel and device. The display panel comprises a plurality of signal lines in a display area and a driver chip which is located in a peripheral area at one ends of the signal lines. The output ends of the driver chip are correspondingly connected with the signal lines through leads one to one. Each lead comprises two metal segments arranged in different layers, and the line width of the first metal segment is larger than that of the second metal segment. In this way, each lead between the driver chip and the corresponding signal line is set as the two metal segments arranged in different layers, that is the driver chip is connected with the signal lines through double-layer lines, so that the display panel can be provided with a narrow bezel. Besides, when the line width of the first metal segment is larger than that of the second metal segment, teh impedance difference between the double-layer lines can be reduced, and the display effect of the display panel is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] As we all know, flat-panel displays have many advantages that other displays cannot match, such as low power consumption, small size, light weight, and ultra-thin screen. The display panel used to realize the display function requires the control of the driver chip to realize the functions of progressive scanning and frame-by-frame refresh, so that the image data input to the display panel can be refreshed in real time, thereby realizing dynamic display. [0003] In the prior art, in order to realize the normal display of the display panel, the driving chip provides driving signals to the signal lines corresponding to the display area through the lead wires in the peripheral area, for example, the gate driver chip and the source driver chip respectively communicate with the gate lines of the display area...
